I think there is a bug ?? the monster stops there and does not let me continue. I really liked the game! Great work.
You have to walk past the monster into the doorway.
It's impossible, it kills me, so can't proceed. But already watched the end of the chapter on youtube. Chapter 2 worked nicely.
You just have to get to that point before the monster does. I experienced this in my playthrough. If he gets to that point, you're kind of screwed.
